Anti-HAX1 antibodies are used in the immunodetection of the protein HCLS1 associated protein X-1. In humans, the canonical protein has a reported length of 279 amino acid residues and a mass of 31.6 kDa. Its subcellular localization is in the cell membrane, nucleus, cytoplasmic vesicles, mitochondria, ER, and cytoplasm. Up to 6 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the HAX1 protein family, HAX1 is known to be involved with cytokine-mediated signaling pathways and the regulation of apoptosis. Synonyms for this target antigen include HS1BP1, SCN3, HCLS1 (and PKD2) associated protein, HS1 binding protein, HS1-associating protein X-1, and HCLSBP1. HAX1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of HAX1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
